Numerical investigation of forced convection of nano fluid flow in horizontal U-longitudinal finned tube heat exchanger

open access: yesIOP Conference Series: Materials Science and Engineering, 2015
A numerical study has been carried out to investigate the heat transfer by laminar forced convection of nanofluid taking Titania (TiO2) and Alumina (Al2O3) as nanoparticles and the water as based fluid in a three dimensional plain and U-longitudinal finned tube heat exchanger. A Solid WORKS PREMIUM 2012 is used to draw the geometries of plain tube heat
